This is a resource that explains the rationale behind the multiple time zone divisions in the United States. Learners will work through a problem set to practice calculating the time in one time zone, given the time in another time zone. This is...(View More) activity 9 from the educator guide, Exploring Magnetism: Magnetic Mysteries of the Aurora.(View Less)

This is a lesson plan for an activity that explores time zone math. Learners will translate their local time to times in other zones around the world and work with the concept of Universal Time, specifically in reference to the reporting,...(View More) description and analysis of solar flares and coronal mass ejections.

How effective would solar cells be in any particular area of the United States? In this activity, students answer that question by analyzing graphs of incoming solar radiation. Students will download two solar radiation graphs, one based on latitude...(View More) and one based on cloud cover. After transferring that data to the accompanying worksheet, students will determine the areas in the United States best suited for the use of solar cells. Using both an overlay graph and a difference graph, students will determine the practicality of solar cell power for a home in various U.S. locations. This lesson uses student- and citizen science-friendly microsets of authentic NASA Earth system science data from the MY NASA DATA project. It also includes related links, extensions, an online glossary, and a list of related AP Environmental Science topics.(View Less)
